Unleashing the Power of JetLogger: An In-depth API Guide for Ultimate Logging Solutions

JetLogger is a powerful and flexible logging library that allows developers to efficiently manage log outputs, errors, and information tracking in their applications. In this comprehensive guide, we’ll dive deep into its APIs and showcase code snippets to demonstrate its capabilities. By the end, you’ll be equipped with the knowledge to integrate JetLogger seamlessly into your projects.

Installing JetLogger

  npm install jetlogger --save

Basic Configuration

Let’s start with a simple configuration on how to set up JetLogger in your Node.js application.

  const logger = require('jetlogger');

  logger.settings({
    mode: 'development',
    level: 'info'
  });

Logging Messages

JetLogger provides easy-to-use methods for logging various levels of messages.

  logger.info('This is an info message');
  logger.warn('This is a warning message');
  logger.error('This is an error message');
  logger.verbose('This is a verbose message');
  logger.debug('This is a debug message');

HTTP Request Logging

JetLogger can log HTTP request details, which is great for monitoring API interactions.

  app.use(logger.httpLogger());

Custom Transports

You can define custom transports to route logs to different destinations.

  const customTransport = new logger.transport.Console({ level: 'debug' });
  logger.addTransport(customTransport);

Format the Log Output

Customize the log output format as per your need.

  logger.settings({
    format: logger.format.combine(
      logger.format.timestamp(),
      logger.format.printf(({ timestamp, level, message }) => {
        return `${timestamp} ${level.toUpperCase()}: ${message}`;
      })
    )
  });

Using JetLogger in an Application

Here is a sample Node.js application demonstrating the integration of JetLogger.

  const express = require('express');
  const jetLogger = require('jetlogger');

  const app = express();

  // Middleware for HTTP request logging
  app.use(jetLogger.httpLogger());

  // Basic route
  app.get('/', (req, res) => {
    jetLogger.info('GET request to "/"');
    res.send('Hello World');
  });

  // Error handling
  app.use((err, req, res, next) => {
    jetLogger.error(err.message);
    res.status(500).send('Server Error');
  });

  const port = 3000;
  app.listen(port, () => {
    jetLogger.info(`Server running on port ${port}`);
  });

By following this guide, you can effectively integrate JetLogger into your applications, enhancing your ability to track and manage logs efficiently. Happy logging!
